The Goerz Taschentenax, also marketed as the Coat Pocket Tenax, is a folding plate camera designed for portability, sized to slip into a coat pocket as the name suggests. It was produced by C.P. Goerz, a German optical manufacturer active in the early twentieth century, and aimed at amateur photographers wanting a compact field camera.

With only a single recorded UK auction hammer result of £25 in 2024, the Taschentenax has limited public price evidence at saleroom level today. Buyers should treat that figure as wholesale — pre-commission — and expect condition, completeness of the bellows, and presence of the original lens to drive what any given example sells for.
